Abstract (en)
[origin: WO2017075403A1] This disclosure provides new methods to characterize and relate residual stress and orientation imparted to the injection molded polymeric preform with orientation and residual stress in the resulting blow molded bottle. The method developed allows one to define and map the coupled thermal stress histories of both processes to define applicable preferred mutual processing windows for both preform and bottle molding processes. Stretch blow-molding parameters are developed using the disclosed method.
